Subject: Mathematics (7) Title: What's the Difference? Subtracting Integers
Description: In Cooperative/Collaborative groups, this lesson will actively engage students to subtract positive and negative integers. An "Essential Question" will be used to activate background knowledge and set the purpose for understanding integers. Students will play board games, use the Internet to play interactive games, and watch videos about subtracting integers.
This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.
Subject: Mathematics (7) Title: Are You INTERESTed?
Description: In this lesson, students will explore simple interest through the use of studying loans and savings accounts. The students will generate the formula I=P x r x t to calculate simple interest on loans. Students will become familiar with "positive" and "negative" effects interest has on reallife applications.

Subject: Mathematics (6  7), or Technology Education (6  8) Title: How Much Money Can I Make?
Description: This lesson is a technologybased activity in which students will research two careers they are possibly interested in pursuing. They will convert the average yearly salary of each career into an hourly wage and record their findings in a spreadsheet. They will calculate their weekly gross and net pay for each career choice.
Subject: Mathematics (7), or Technology Education (6  8) Title: Investigating Integers
Description: Students will create a multimedia presentation to demonstrate their understanding of integers. Within this presentation they will include information on how to compare and order integers and how to add and subtract integers by writing about situations where they may encounter integers. Additionally, they will create a word problem with a solution that reflects their understanding of adding or subtracting negative and positive integers.
